SAFE-CLOSING MEANS.

To all whom it may concern:

Be it known that I, GEORGE A. IIn'rirnns- LEY, a citizen of the United States, and residing at Norwood, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Sale-Closing Means; and I do declare the 'following to be clear, full, and exact descri tion oi the invention, attention being calle. to the accompanying drawing, with the reference characters marked thereon, which form also a part of this speciiication.

This invention concerns improvements in the construction of safes oi a type illustrated in ,Patent No. 905,180, and in which patent the construction of certain means is described for holding the door of a sate in position when seated to close the opening provided or it in the safe-body.

The invention relates to certain improvements which are applicable to the invention described in said patent, so that one may be used in connection with the other.

In the following specification and particularly pointed out in the claims at the end thereof, is found a full description ot my invention, together with its parts and manner of construction, which latter is also illustrated in the accompanying drawing, in which Figure 1, shows in -iront-view a customary safe with its circular door partly open. Fig. 2, is a side-view of the safe shown in the preceding figure with parts partly broken away. Fig. 3, is a sectional detail view of a part of the closing-means.

In the drawing, A represents the safe-body, and a, is the front-wall thereof. B is a circular door-opening within this front-wall. The Surface of this latter' which surrounds the opening, and forms the seat for a door is shaped to form a tapering jamb t. O, is the circular door fitted to this opening, its edge c, being tapering and litted to seat against the tapering jamb l), within the opening. This door is carried in a rinol or circular frame D, in which it is supported for rotation in a manner customary in screw-door-salies. The ring hangs between vertically alined trunnion-bearings d, formed on the usual crane- 'frame E, which is supported by hinges e, on the front-side of the safe-body. The door, for o ening or closing, is manipulated by a hand e F, on the crane-frame whereby it is swungto or from its opening. For holding Sp ecicaton of Letters Patent.

' the door to its scat in this opening, I provide a screv--connc the coinpleinontary parts of which are provided en the tapering surlaces et the door and .its jamb respectively. By preference I use a plurality of threads which are equally diviced around the ciiouinterence and have shown two, which start and terminate at points diametrically opposite each other. ",l-'he circumferential extent ol" thc threads may be so that they pass partly or entirely around the surfaces on which they are provided. When one thread is used it should at least pass once around the entire circumference so that the door has a screw-connected bearing all around. In the form shown, thc two threads are so arranged that they together provide such a continuous bearing.

Since the tapering surfaces of thc door and its jainb are closely iitted to each other by a ground joint, the door being ground into its opening, it becomes necessary to provide the projecting or male part el the thread in form of a separate member which is placed in position alter the door has been ground to its seat. In the case illustrated I provide two of these members and designate them hereafter as tongues G, each appropriately shaped and curved to a screwpitch and which tongues are rigidly secured in grooves g, provided for them. These tongues in the resent case being provided in the door-jamo, said grooves are located accordingly in said jamb, the tongues after insertion projecting above the surface thereof. rlhe complementary grooves which receive the projecting part of these tongues when the door is closed are provided in the tapering side of the doei' as shown at H, II, and have also a screw-pitch corresponding to the pitch of the tongues. These grooves run out to the open as shown at 7L, 7i, where they permit the tongues to start their entrance. rIhis entry of the tongues is caused by rotation of the door which is done in the usual manner applied in serew-door-safes. When screwed home, the door is Iirmly held in its opening against movement in an axial direction. It is locked in this closed position by the usual bolt mechanism (not shown) provided in the door, the ends of the bolts entering sockets K, one socket only appearing in Fig. 2. The bolts may be operated by a time-lock mechanism or otherwise.

It is essential, when the door is lully screwed home, that the ends of' these holts have arrived opposite these sockets K, so as to he capable of entering them. This Vrequires adjustment, ahsolutely accurate, of the position of the tongues Within theirl `complementary grooves With reference to the position of the bolts and their sockets. Under the present conditions and particularly with an integral male-thread the obtention oi this adjustment is connected with many difficulties and requires much time-consuming labor hy tiling and grinding Yto i'it the exact position. The provision of the male-thread in 'form oi an adj ustahle memher which may he shifted length-Wise in its groove goes far toward solving this perplexing problem. A tongue may he shifted length visel in its groove to the proper position, and if too long, it may se cut off, the vacant space in groove g, heing i'illed out by means of a Wedge-shaped insert L, as shown in Fig. 3, Which is fitted into this space and serves to hold the tongue irinly in position. rllhe same may he done if hy use and Wear the proper fit should he lost When this insert may he Withdrawn and ai'ter the tongue has 1neen adjusted, another Wedge is inserted. it permits also changes in the size (Width), of the tongue and shape of its pitch if such is necessary. All the ivorl for iitting, and linishing now done hy cutting or iiling, may he done hy grinding and since no inachine-tool-Work has to he done, this construction is excellently 'Well adapted for use on sales which are made ol non-machinahle metal like manganese steel for instance. ln such case, tongues G, also he made of the same material like the body of the safe and ground to shape.

Having described my invention, I claim as new:

1. in a safe having a circular door-opening With a tapering door-jarnh and a circular door litted to this jamb, the opposite surfaces of hoth being each provided With coniplernentary screw-pitched grooves which, when the door is seated, are opposite each other, tongues adapted to occupy simule taneously vthese opposite grooves, they heing shorter thanthe grooves to permit ad.g justnient for being fitted, and means provided in the grooves in one of the surfaces to fill the space therein which is not occupied hy the tongues, and serving for the purpose to hold these latter rigidly in position.

2. in a safe having a circular door-opening with a tapering jamo Which is provided with screw-pitched grooves, tongues fitted to these grooves and projecting above them, the grooves lacing longer to permit the tongues to he adjusted lengthwise in them if necessary for i'itting, Wedge-shaped inserts to iill the space in these grooves not occupied hy the tongues and` serving to rigidly secure them in these grooves after adjusted, and a door iitted to the door-opening and provided with grooves in its tapering edge compleinentary to the tongues and adapted to receive their projecting part.

in testimony whereof, l hereunto afliX my signature in the presence of tWo Witnesses.
